Title: A stator for a gas turbine compressor
Inventor: BROMANN ALAIN MARC LUCIEN
IPC: F04D29/58
Filed: 1998-03-16
Abstract: The compressor has a stator made up of a casing formed  by  an  assembly  of  parts  (7)  in  a  circular arrangement  and assembled using  longitudinal  flanges (2) and sectors (5) demarcating the flow path of gases and  fixed to  the  casing  sectors  by  hooks  (8,  9) demarcating substantially air tight chambers (13). The layer  of  air  held  in  this  way,   and  which  is substantially continuous,  reduces the transmission of heat to the casing and reduces irregular expansion at its surface which would have the effect of increasing the clearances between the ends of the rotor blades and the stator (6 and 14) and of reducing the efficiency of the machine.

Abstract: Whole kernel corn is ground and sifted to separate a coarse particle fraction which is then heated with lime and water to a temperature of at least 71°C and below 100°C, preferably about 99°C or less, for up to about 15 minutes.  A fine particle fraction from the sifting step can be combined with the heat treated coarse fraction. The resulting heat treated mixture is then dried under a vacuum while continuously mixing for at least about 20 minutes to obtain a dried masa flour having a moisture content of about 7% to about 12% by weight.  Thereafter, the dried masa flour can be ground while maintaining the temperature below the gelatinization temperature to reduce the particle size of the masa flour without further gelatinization.

Title: Safety device for the fuze of a spin-stabilized projectile
Inventor: ROOSMANN KARLHEINZ
IPC: F42C15/188
Filed: 1998-06-24
Abstract: The present invention relates to a safety device (1) for the fuze of a spin-stabilized projectile, said projectile having a detonator carrier (10) that can pivot from a safety position into a firing position.        In order to make it possible to lock the detonator carrier (10) in the firing position in a simple manner, despite the application of only a little force and a high degree of stiffness, the present invention proposes the integration of pivotable locking lever (15) into the safety device (1), this locking lever being actuated and pivoted by the detonator carrier (10) when the detonator carrier is pivoted. As soon as the detonator carrier (10) has reached the firing position, a detent catch (16) that is formed on the locking lever and appropriately shaped engages in a cutout (21) in the detonator carrier in such a way that the detonator carrier (10) cannot pivot back.

Title: Method for unlicensed band port to autonomously determine interference threshold and power level
Inventor: NOERPEL ANTHONY R
IPC: H04B7/005
Filed: 1996-03-27
Abstract: Radio ports (RPs) in an unlicensed personal communications system adaptively , autonomously set their interference threshold and/or transmission power levels. This may be done by the RP measuring the signal level on each of the  available channels and then setting the interference threshold and/or power level according to these measurements. In a preferred method (600), the interference threshold is determined by measuring the signal level on each channel (604), ranking the channels in order of measured signal level, and using these rankings to determined the threshold (606). The transmission pow er level may be set with reference to the adaptive interference threshold level . This level is determined by using the system and FCC power limitations and current conditions to provide a satisfactory transmission level.

Abstract: The present invention is directed to a method for stabilizing the flavor of a fermented malt beverage, most particularly a beer, by the addition of one or more inhibitors, blockers, reducing agents or binding agents that inactivate one or more Maillard reaction intermediates that induce staling of the flavor of fermented malt beverages. In preferred such methods, the agents used are reductase enzymes, especially aldehyde reductases, carbonyl reductases, aldose reductases,oxoaldehyde reductases and most particularly oxidoreductases such as isozymes of Old Yellow Enzyme (e.g, OYE1 and OYE2). The invention is also directed to the fermented malt beverage prepared by such a method, and to the use during the brewing process of reductase enzymes from naturally occurring sources, including those produced by yeasts, to stabilize the flavor of the resulting beer product and to produce a beer having a stable flavor. The invention also relatesto cells which have been specifically modified, selected, or genetically engineered to express or secrete a reductase enzyme which may be used during the brewing process to stabilize the flavor of the resulting beer product and to produce a beer having a stable flavor. The invention also provides fermented malt beverages having enhanced flavor stability produced by these methods.
